Torque fasteners
Heat generated by improper terminal torque is a
leading cause of equipment failure. Torque
terminals to the values shown in the table.
Once torqued to the proper value, draw an “X”
across the fastener head and the surrounding
metal surface so you can visually check whether
the fastener has changed position and may require
attention. Bolts torqued at the factory will be
marked in the same way.
The torque tables apply to horizontal component
screw connections, vertical bus bar screw
connections, electrical terminal connections and
structural components of the Emax Link 2
Abbreviated LV Switchgear.
Note: For equipment connections and mountings,
see the manufacturers’ technical data sheets.
